Low pressure will lift out of the Tennessee Valley on Saturday and head towards the Mid Atlantic coast.  Mainly dry conditions are expected across the Twin Tiers on Saturday with cloudy skies and temperatures in the 40s.  Colder conditions will filter into the region on Sunday with the chance for a wintry mix.  Precipitation amounts on Sunday will be on the light side, however, there's the potential for some ice to mix in with snow showers which could cause slick road conditions.
